Discovered: The mini-meleon that is one of the smallest reptiles on the planet
Share this article Share While there is no permanent fresh water supply, the snakes have, scarily so, adapted to the conditions and survive with minimal water. While there is no evidence as to how the snakes initially arrived to the area, it is rumoured that a man named Lindsay ‘Rocky’ Vane dumped his tiger snake collection on the island in after his first wife died of a tiger snake bite.
The snakes should not be approached under any circumstances, and are the fifth most venomous in the world Attenborough noted that majority of the island’s snakes were in fact blind. This is caused by birds defending their chicks by pecking at the snakes’ eyes. In contrast to what one would expect of a blind animal, the snakes were not negatively impacted by their blindness, simply relying more heavily upon scent, feasting on immobile prey.
Carnac island is thus far the only place that Attenborough has noticed this.
According to Luffy, Alvida. Subverted by how he still wasn’t interested after she became drop dead gorgeous. The most prominent example in One Piece is the warthog zombie Lola, whose entire fighting style revolves around stealing kisses from her beloved Absalom. She’s also a subversion however, as she turns out to be a very sympathetic character, while Absalom is portrayed as a perverted Jerkass. The real Lola is this as well, though she’s not as Ax-Crazy as her zombie was.
Franky plays an advance from her cool, saying he’s too ” super ” for anything to work out between them.

Not only does the finding have implications for studying human virology in the future, it also shows that viruses have an evolutionary history dating back millions of years – and they evolved concurrently with vertebrates. Although some RNA viruses have previously been found in newts and salamanders , little research has been conducted into viruses that affected other amphibians, fish and reptiles.
Holmes and his team looked at the RNA of over species, including reptiles such as snakes, turtles and lizards; amphibians such as frogs, salamanders and caecilians; and fish such as jawless, cartilaginous, ray-finned, lancelets and lungfish. Twenty-four percent of those viruses were recovered from different tissues within the same individual. Humans and fish are very different from one another – and further analyses of the viruses revealed that they had been evolving alongside the animals they infect, arriving on the scene at the same time as vertebrates.

Oldest-known aquatic reptiles probably spent time on land September 19, , Frontiers Drawing of Mesosaurus. The fossilized bones of adult Mesosaurus share similarities with land-dwelling animals, which—coupled with the relative scarcity of land-weathered fossilized remains of large specimens—suggests that older mesosaurs were semi-aquatic, whereas juveniles spent most of their time in the water.
This new research emphasizes the importance of thoroughly analyzing fossilized remains from across all stages of a reptile’s life to get a full appreciation of its lifestyle and behavior. She continues, “We then realized that in comparison to the smaller, better-preserved specimens, larger Mesosaurus fossils were almost always disarticulated, very weathered and badly preserved. This suggested these larger specimens had extended exposure to the air when they died. Terrestrial, semi-aquatic and aquatic animals show a clear difference in bone profiles, so they used morphometrics to analyze the shape of the fossilized bones.
Forty Mesosaurus specimens, from juveniles to adults, were examined and their bone profiles compared to those of similar reptiles known to be aquatic or semi-aquatic, such as crocodiles and marine iguanas. This supports the hypothesis that the oldest and largest mesosaurs spent more time on land, where fossil preservation is not as good as in the subaquatic domain.

Notice the inclusion of amphibians below the crocodiles. In the 13th century the category of reptile was recognized in Europe as consisting of a miscellany of egg-laying creatures, including “snakes, various fantastic monsters, lizards, assorted amphibians, and worms”, as recorded by Vincent of Beauvais in his Mirror of Nature.
This was not the only possible classification scheme:
Frog with no croak among reptiles and amphibians facing extinction. The British and Irish Association of Zoos and Aquariums (BIAZA) has published the list of reptile and amphibian species.
Carbon , Radiometric Dating and Index Fossils Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.
Carbon dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things. Carbon is a radioactive isotope of carbon. The half-life of carbon is approximately 5, years. The short half-life of carbon means it cannot be used to date fossils that are allegedly extremely old, e. The question should be whether or not carbon can be used to date any artifacts at all?
The answer is not simple. There are a few categories of artifacts that can be dated using carbon ; however, they cannot be more 50, years old. Carbon cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air. This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock. The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.

Share this article Share The sluggish progress of the reptiles has helped scientists build up a genetic picture of the archosaurs that predated dinosaurs, pterosaurs, birds and crocodilians. The study, published in the journal Science, suggests that the ancestor of all archosaurs had an extremely slow rate of molecular evolution, which sped up in the bird lineage.
After the meteor strike, which is thought to have wiped out the dinosaurs 66 million years ago, surviving birds experienced a rapid burst of evolution.
With fossil records dating over 20 million years old that are hardly changed from the water dragons seen today, they are likely Australia’s most primitive dragon species. They eat a range of foods including carrion, insects, small mammals and birds, and fruits and vegetation.

These 215 fossil pterosaur eggs are revealing new clues about these mysterious flying reptiles
The history of reptiles is ancient, dating back hundreds of millions of years, when snakes descended from 4-legged creatures, and turtles looked relatively the same! Ezulwini Game Lodges , located in the diverse Balule Nature Reserve, enjoy numerous reptile sightings, particularly crocodiles, which are often seen basking on the banks of the Olifants River. These giant, scaly creatures are feared for their vicious teeth and vice grip they place on their prey.
They lie in wait of the perfect opportunity to pounce, which is an incredibly quick movement, leaving little room for escape. Rock monitors, also known as legavaans, are large lizards with dangerously strong tails, which they use for defence. They have a widely varied diet, preferring to snatch up whatever they can find, and often!
New images of the “alien mummies” were unveiled during a press conference called “The mummies of Nazca” in Peru by Mexican ufologist and journalist Jamie Maussan on Tuesday. YouTube Five 1, year-old mummies which allegedly look more reptilian than human have been causing a stir with conspiracy theorists YouTube X-rays of the so-called mummified remains were shown during a press conference to banish claims that they were fake This included X-rays of the mummified remains so Maussan could banish claims that they were fake or made of plaster, Ruptly has reported.
Mr Maussan alleges that of the five bodies discovered, three of them had “characteristics that are closer to reptiles than humans”. YouTube While some have said they will keep an ‘open mind’ about the ‘alien mummies’ others have branded them as fake YouTube Mexican ufologist and journalist Jamie Maussan held the press conference and claimed that a total of five of these so-called mummies had been discovered in the last two months The video was posted by website Gaia.
One viewer reported commented: The corpse looks like it was made of plaster.
Carnivorous reptiles swallow little animals and insects whole without masticating, while herbivorous reptiles face the same problem, only with plants. Digesting a whole animal, bones, fur and all, can be a burden on the digestive system. Periods of Fasting Large reptiles, such as crocodiles or boa constrictors, do not eat daily. They go for long periods, up to and even longer than six weeks, between meals, and then eat something massive, like a whole animal.
Reptiles roamed the Earth millions of years ago, and continue to fascinate people young and old to this day. There are many interesting animal facts about reptiles that often go overlooked.
Reconstruction Terrestrial reptiles and the first mammals On land the vertebrates are represented in the Triassic by labyrinthodont amphibians and reptiles, the latter consisting of cotylosaurs, therapsids , eosuchians, thecodontians , and protorosaurs. All these tetrapod groups suffered a sharp reduction in diversity at the close of the Permian; 75 percent of the early amphibian families and 80 percent of the early reptilian families disappeared at or near the Permian-Triassic boundary.
Whereas Early Triassic forms were still Paleozoic in aspect, new forms appeared throughout the period, and by Late Triassic times the tetrapod fauna was distinctly Mesozoic in aspect. Modern groups whose ancestral forms appeared for the first time in the Middle and Late Triassic include lizards, turtles, rhynchocephalians lizardlike animals , and crocodilians. The mammal-like reptiles, or therapsids , suffered pulses of extinctions in the Late Permian.
The group survived the boundary crisis but became virtually extinct by the end of the Triassic, possibly because of competition from more-efficient predators, such as the thecodonts. One of the best-known of this group was Lystrosaurus , whose fossils have been found in India, southern Africa, and Antarctica. LystrosaurusTherapsids, such as Lystrosaurus, were mammal-like reptiles that thrived early in the Triassic Period million to million years ago. The first true mammals , which were very small, appeared in the Late Triassic the shrewlike Morganucodon, for example.
Supplied SOME large, grass-eating mammals, such as elephants, rhinos and camels, gather together not only when they eat, but also when they defecate. The group poop, researchers have surmised, has several important functions. One is hygiene, to prevent the emergence of new parasites; another is safety, to provide surveillance in numbers against any prowling predator.
Reptiles are one of the most ecologically and evolutionarily remarkable groups of living organisms, having successfully colonized most of the planet, including the oceans and some of the harshest and more environmentally unstable ecosystems on earth.
By Amina Khan Nov 30, 5: A study of these remains helped scientists learn how these flying reptiles developed and whether they were involved parents. The find, described in the journal Science, offers an unprecedented look at the early development of these ancient flying reptiles. They lived from the late Triassic to the end of the Cretaceous roughly million to 66 million years ago.
Scientists have discovered a number of fossil dinosaur eggs, and found that the large marine reptiles called ichthyosaurs actually gave birth to live young. But the biology and development of pterosaurs, even with the discovery of a handful of non-flattened eggs in recent years, has remained something of an enigma. A visualization of the bones inside a pterosaur egg.
But a mother lode of hundreds of eggs and bones discovered in a sandstone block in northwestern China may finally paint a fuller picture of these animals at the earliest stage of their lives. All the specimens seem to be roughly million years old, dating back to the Early Cretaceous period , and appear to belong to the same species: The researchers counted eggs but there may be up to , given how the eggs are piled on top of each other. The eggs show some cracking as well as crazing the fine network of fractures often seen on glazed pottery.
